BS870-HXY

HXY MOSFET · MOSFETs · SOT-23

BS870-HXY from HXY MOSFET, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 G input Gate; gate-source voltage limit is ±20 V, with a gate threshold of 0.7 to 1.9 V at 250 µA and ESD rating HBM ≥2000 V.
2 S passive Source; continuous drain current is 0.3 A at TA=25℃ and body-diode forward current is 0.3 A.
3 D passive Drain; drain-source voltage is 60 V maximum, continuous current is 0.3 A and pulsed current is 0.8 A.
